WILLIAM S. BULLEN, 0F INDIANAPOLIS, INDIANA, ASSIGNOR TO HIMSELF AND STEPHEN A. CLARK, OF SAME PLACE.

MACHINE FOR CREASING- LEATHER.

Specification of Letters Patent No To all whom it may concern:

Be it known that I, WILLIAM S. BULLEN, of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Creasing-Machines for the Use of Carriage-Trimmers, Harness -Makers, and other lVorkers in Leather; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in substituting chased rotary disks of metal for the old and time-honored creasing tool and so operating said disks as to make the whole designat one passage over the leather, all 'of which I do by the simple process of turning a crank.

To enable others skilled in the art, to make and use my invention, I will proceed to describe its construction and mode of operation; and, in vthis description, I desire that the accompanying drawings shall constitute a part and parcel of said specification, and in every instance where reference is made to a part of my machine by letter, I wish it understood that each like letter refers to a like part.

Figure l, is an elevated perspective view of my entire machine (with a small portion of the table cut away so as to show the large propelling roller beneath saidtable). Fig.

2, is a combination of circular disks whichare used for creasing as they appear on the edge. Fig. 3, is the diameter view of the creasing disks, as seen in Fig. 2. Fig. 4, is an edge view of a single disk. Fig. 5, is the thimble, or spool upon which the creasing disks revolve; and Fig. 6, is the shaft which passes through the thimble or spool, Fio. 5.

Il, is the table, upon which my creasing wheels, and all their appurtenances are arranged. This table'is supported by four legs of anyl desired length. These legs must be long enough to give a clear and free sweep to the crank B, is a crane neck bracket one end of which is firmly fastened by screws to the table (A,)-and the other endcarries the 30,7555, dated November 27, 1860.

up and down by the screw (D) and carries the creasing disks by means of which they are adjusted to suit the thickness of the leather, which passes between them and the roller (F), as seen in Fig. l.' The roller (F,) is revolved by turning crank which is fastened on the right-hand end of the shaft (G.) The pin, or shaft (J,) passes through the thimble, or spool (I) and upon it the said spool fits loosely.

It will be seen that the creasing disks may be made of any desirable pattern, so far as the chasing on their periphery is concerned; and since each one is independent of all the others, and all of the same diameter, they may be changed to suit the taste of the operator, and so compounded as to vary the designs to almost any extent.

The mode of operation is simple, viz: Having placed the leather (to be creased) between the creasing disks (E,) and the roller (F,) in (Fig. 1,) turn down the screw (D) until the leather is tightly compressed, then by turning the crank the leather is forced through between the roller and creasing disks in such manner as to make a firm and lasting impression. n

The advantage of this expeditious mode of doing this kind of work, is self-evident. By this means, the work of a whole day (with the old fashioned ticler,) can be done in ten or fifteen minutes; and, when done, is far more systematic and uniform.

This machine is designed for carriage trimmers, and other workers in leather, and, having thus fully described the nature of my invention and the mode of its operation Vhat I claim as new, and desire to secure by Letters Patent, isd

The combination and arrangement of a series of creasing disks, upon, and with spool or thimble (I,) when these are made to revolve upon axle (J,) substantially as shown, and for the purposes designated.

W. S. BULLEN.
